"This was a strategic move," said Chris Marion, product manager at Adult Rental. "We maintain a focus on quality and strongly considered our market research in selecting these partners. These five studios all bring specific niche content to the table, representing themes and topics our customers enjoy. The real trick is not to have your hand guided by personal biases, however subtle they may be."

Adult Rental targeted the five studios because it feels they're all at the forefront of their particular genres, consistently producing excellent work, said Marion. "With their fresh titles, our bondage, reality, teen, anal and big tit sections have never looked better," he added.

In addition to the roster change, Adult Rental said it continues to think outside the box when guiding surfers to their exact target, due to the competitive nature of the industry.

"To manage the sheer volume of our microniched content, we have launched our new Ajax Custom Theatre Designer, which is currently in open beta," Marion explained. "It allows webmasters to creatively market a subset of the titles on offer by utilizing specific niches with custom layouts and designs. This helps target genre-inclined traffic."

Adult Rental currently offers $35 per sign-up, or 35 percent revshare, with no cross-sales, pop-ups or dialers.
